JPS5931319A - Construction of strip footing for building - Google Patents

Abstract

PURPOSE:To simplify the carrying-in operation of materials for a strip footing by a method in which other vent ports and the rising portion of strip footing for general foundation are formed by leaving a vent port serving as a path through which materials are carried in, and lastly, the vent port serving as the path is constructed. CONSTITUTION:A strip footing 11 is constructed of vent ports 11a, 11b, 11c, and 11d and a general fundation 11e. The vent ports 11a, 11b, 11c, and 11d are provided with a vent port 12 having a vent port iron-bar set unit 16 with an iron bar lattice 15. When concrete is placed for the vent port 11a and the general foundation 11e, plates (not illustrated) are laid across excavated trenches (not illustrated) for the vent ports 11b, 11c, and 11d to form a path 19, and by utilizing the path 19, materials necessary for constructing a strip footing 11 are carried in. After the completion of construction of the foundation 11e and the vent port 11a, the vent ports 11b and 11c are constructed and lastly the vent port 11d is constructed to complete the construction of the strip footing 11.

Description

[Detailed description of the invention] The present invention relates to a first method for constructing a dyed fabric foundation.

Conventionally, when laying the foundation for building a building, a method has been adopted in which the foundation is constructed all at once over the entire site on which the building is to be constructed. At this time, the foundation 1 to be built t1q is first cut by root cutting υ, as shown in Figure 1.
After doing this, lay chestnut stone, etc. at the bottom of Nekiri i'i'# 2 and tamp it down, set formwork 3.4 on top of it, then transport the concrete with a concrete cart etc. and pour the concrete. It can be completed.

However, due to the topography and surrounding conditions, there are cases where materials and equipment necessary for foundation 1 tlIri must be carried into the site using the site where the building is being constructed, or where external construction is required as shown in Figure 2. Eflb cloth foundation 6 inside the foundation 5
If there is an independent foundation 7, an external foundation 5-1 is fine, but especially an internal foundation 6, an independent foundation? When carrying out tM'J of #7, concrete, other materials, and equipment must be carried in such a way as to straddle the external fabric foundation 5, so the formwork 4 of the external fabric foundation 5 gets in the way and the quality and quality The disadvantage is that the process of transporting the equipment is very troublesome.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to transport the negative phase and equipment necessary for constructing a foundation into the site where a building is constructed. An object of the present invention is to provide a method for constructing a building fabric foundation that can be easily transported. Hereinafter, the present invention will be specifically explained with reference to the drawings.

3 to 6 show an embodiment of the present invention,
11 is a cloth curtain (TRI) made of concrete, and this cloth curtain foundation 1 has ventilation openings 11a, llb, 110, lid.
and general basics ff1i 11e.

The ventilation openings 11&, llb, llc, and 1lcl are the parts that form the ventilation [:J12].
A ventilation opening reinforcement unit 16 is constructed by attaching a reinforcing bar grid 15 in which reinforcing bars or wires are laid out in a lattice shape to two parallel reinforcing bars 3.14. It is provided. In addition, the ventilation opening part 11a and the general foundation part lie
Conch! In one prefecture of J-t'l''J installation, ventilation opening part 11
b, 110, and lid are used as the N+'+ road 19 by laying a board 18 so as to straddle the root cut U417. The general foundation part lie is a part of the cloth foundation 11 other than the part forming the ventilation opening 12, and inside thereof there are two horizontal stripes 20.
A general foundation reinforcement unit 22 is provided in which vertical reinforcements 21 are assembled in a ladder shape. Further, in the lower part of this general foundation reinforcement unit 22, insert reinforcements 23 provided at regular intervals are filled with chestnut stone and gravel at the bottom of the root cutting groove 17, and a layer of chestnut stone is formed. 2
Anchor bolts 25 are inserted at predetermined intervals in the upper part of the general foundation reinforcement unit 22. Roughly speaking, the cloth foundation 11 is divided into a footing part 26 and a rising part 27, and the footing part 26 is connected to the formwork 28.
The rising portion 27 is formed by pouring concrete between the molds 290.

The prefecture that will construct the cloth foundation 11 configured as above!
, explain about yourself. First, root cutting is carried out over the entire area of the site where the building is to be constructed, and chestnut stone and gravel are spread and compacted at the bottom of the root cutting groove 17 to form a chestnut stone layer 24 1u. (2) The general foundation reinforcement unit 22 is installed on the chestnut layer 24 of the general foundation txe, and the cloth foundation 11
After a formwork 28 is provided on the rock layer 24σ], concrete is brought in and concrete is removed to construct the footing portion 26. Further, ventilation port portions 11b, 110.
Lay the board 18 so as to straddle the root cutting groove 17 of 11a,
After forming the passage 19 and bringing in the materials and equipment necessary for constructing the cloth foundation 11, the formwork 29 of the general foundation part 110 is installed.
At the same time, the replacement reinforcement unit 16 and the formwork 29 were installed in the ventilation opening part 11a, and concrete was poured in order from the upper right to the lower left in Figure 3.
7! F4 IQ. In this way, the ventilation opening part 11a
After the construction of the general foundation part 1 is completed, next is the ventilation opening part 1.
Install the ventilation opening reinforcement unit 16 and formwork 29 on 1b,
And concrete is poured and the rising part 27 is $1/f.
'4S.

When the construction of the ventilation port part 11b is completed, the ventilation port part 11
0, the ventilation opening reinforcement unit 16 and the formwork 29 are installed, and concrete is poured to construct the rising part 27. Then, when the seventh step to the ventilation opening section 11Q is completed, (9)
Ventilation
- Build the start-up section of the first section lid.

Finally, once the concrete has solidified, formworks 2B and 29 are removed, and the cloth foundation 11 is completed.

In addition, when there is an independent foundation inside the cloth foundation 11, what is necessary is just to construct an independent foundation at the same time as construction of the general foundation part 11(theta) and the ventilation opening part tia.

As explained above in Explanation 1, the present invention
Leaving the ventilation opening part that should be h, form the rising part of Ilj i'pj in sequence, and finally form the rising part of the cloth foundation of the entrance and exit of the passage and the ventilation opening part 1 and cloth ^1 ]＾Park 1
Collection 1: "Because it is designed to be built, it is easy to carry materials and equipment necessary for constructing a foundation into the IL." It has the excellent effect of being able to
